CNMI Mirror Code: federal income tax laws apply in CNMI as territorial income tax, in the same manner as Guam

“Section 601. (a) The income tax laws in force in the United States will come into force in the Northern Mariana Islands as a local territorial income tax on the first day of January following the effective date of this Section, in the same manner as those laws are in force in Guam.”

Note: The CNMI Mirror Code operates via the Guam Mirror Code (48 U.S.C. § 1421i) as the template. IRC references to 'Guam' automatically extend to CNMI per § 601(c): 'References in the Internal Revenue Code to Guam will be deemed also to refer to the Northern Mariana Islands, where not otherwise distinctly expressed or manifestly incompatible with the intent thereof or of this Covenant.' This incorporates the full Subtitle A of the IRC, including IRC § 1(h) (the 0%/15%/20% LTCG rate schedule) and the 12-month holding period under IRC § 1222. Tax is paid to the CNMI government, not the federal treasury. No CNMI-specific modification to capital gains rates found in federal statute.

CNMI taxes FNMA and FHLMC bond interest: CNMI Mirror Code incorporates federal IRC including gross income rules; 31 U.S.C. §3124 preempts only direct U.S. obligation taxation; FNMA/FHLMC are not U.S. government obligations

“Stocks and obligations of the United States Government are exempt from taxation by a State or political subdivision of a State. The exemption applies to each form of taxation that would require the obligation, the interest on the obligation, or both, to be considered in computing a tax.”

Note: CNMI Mirror Code (48 U.S.C. § 1801, Covenant § 601) incorporates IRC Subtitle A via the Guam template: FNMA/FHLMC interest is in federal gross income (not IRC-excluded). 31 U.S.C. §3124 exempts only 'obligations of the United States Government'; FNMA and FHLMC are GSEs with no bondholder exemption statute. No CNMI DRT ruling found.

CNMI Mirror Code incorporates IRC §1(h)(11) but domestic-corporation substitution may exclude US mainland corporation dividends from the preferential rate; treatment unresolved

“The income-tax laws in force in the United States of America and those which may hereafter be enacted shall be held to be likewise in force in Guam.”

Note: CNMI uses a mirror-code tax system under the Covenant with the US; preferential rates from IRC §1(h)(11) apply as if the CNMI were a state. The uscode.house.gov page for 48 U.S.C. §1801 now returns docnotfound, so the URL was swapped to the working 48 U.S.C. §1421i(d)(1) page; the quote is the Guam mirror-code template that the CNMI Covenant §601 mirrors. Under mirror-code substitution, 'domestic corporation' in §1(h)(11) may be read as a CNMI-incorporated corporation; whether dividends from US mainland corporations qualify for preferential rates is unresolved; no authoritative IRS or CNMI DRT ruling exists. This differs from GU and VI where prior research found a clearer basis for preferential treatment.

FHLB and FFCB bond interest exempt from CNMI taxation: federal enabling statutes mandate state tax exemption

“Any security issued under this chapter by a Federal home loan bank, including the stock thereof, shall be exempt from taxation, except taxes upon real estate, by any State, county, municipality, or local taxing authority.”

Note: 12 U.S.C. §1433 says 'any State, county, municipality, or local taxing authority'; that clause refers to sub-state political subdivisions, not U.S. territories. CNMI is bound by §1433 and §2023 under the Supremacy Clause (U.S. Const. art. VI, cl. 2): federal enabling statutes bind territorial governments. See also constitutional intergovernmental tax immunity (McCulloch v. Maryland, 17 U.S. 316 (1819)). No CNMI DRT ruling found.

Farm Credit Act: notes, bonds, debentures, and other obligations of Farm Credit Banks are instrumentalities of the United States exempt from all State, municipal, and local taxation

“The mortgages held by the Farm Credit Banks and the notes, bonds, debentures, and other obligations issued by the banks shall be considered and held to be instrumentalities of the United States and, as such, they and the income therefrom shall be exempt from all Federal, State, municipal, and local taxation, other than Federal income tax liability of the holder thereof under the Public Debt Act of 1941 (31 U.S.C. 3124).”

Note: 12 U.S.C. §2023 explicitly covers 'the income therefrom' (i.e., interest payments to bondholders), exempting it from all State and local taxation. The only carve-out is federal income tax on the holder. Parallel to 12 U.S.C. §1433 (FHLB Act), which exempts FHLB securities from state taxation. Together §1433 and §2023 mandate state and local tax exemption for both FHLB and FFCB bond interest.
